Spectro-Polarimetric Properties of Sunquake Sources in X1.5 Flare and Evidence for Electron and Proton Beam Impacts
Alexander G. Kosovichev, Viacheslav M. Sadykov, John T. Stefan
The first significant sunquake event of Solar Cycle 25 was observed during the X1.5 flare of May 10, 2022, by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics…
Can Proton Beam Heating Flare Models Explain Sunquakes?
Viacheslav Sadykov, John Stefan, Alexander Kosovichev +4
SDO/HMI observations reveal a class of solar flares with substantial energy and momentum impacts in the photosphere, concurrent with white-light emission and helioseismic responses…
Toroidal Magnetic Flux Budget in Mean-Field Dynamo Model of Solar Cycles 23 and 24
V. V. Pipin, A. G. Kosovichev
We study the toroidal magnetic flux budget of the axisymmetric part of a 3D mean-field dynamo model of Solar Cycles 23 and 24. The model simulates the global solar dynamo that incl…
Statistical Study of the Correlation between Solar Energetic Particles and Properties of Active Regions
Russell D. Marroquin, Viacheslav Sadykov, Alexander Kosovichev +9
The flux of energetic particles originating from the Sun fluctuates during the solar cycles. It depends on the number and properties of Active Regions (ARs) present in a single day…
Predicting Solar Proton Events of Solar Cycles 22-24 using GOES Proton & soft X-Ray flux features
Aatiya Ali, Viacheslav Sadykov, Alexander Kosovichev +9
Solar Energetic Particle (SEP) events and their major subclass, Solar Proton Events (SPEs), can have unfavorable consequences on numerous aspects of life and technology, making the…
